` the freund the tubular .portion of the lubricant4 head 11 and are conformed and secured thereto' by the clamping ring 17 and the collar 18. The last two mentioned ineml: s are connected together by a screwthreaded 4joint 19. The adjacent. edges ofk the askets 15 and 16 lare flanged outwardly as shown4 at 20 and 21 and clamp between opposing portions of the ring 17. and the collar 18. y v w The gasket 16 has .a portion extending across a flattened face '13 and in spaced relation thereto, and is provided with a discharge orifice 22 which communicates with y passageway extending through the head 11. @The collar 1S is provided with an out- Wardly extending cylindrical extension 23, the outer edge of which is flanged inwardly as shownl at 24, to provide a bifurcated member which is adapted to surreceivingdevice 25.

The lubricant receiving device 25 coni- "prises a tubular portion .having screw threads 26 at one ,end for securing it to. al

bearin to be lubricated, and a head 27.at the ot er end, which is adapted to be in- -serted between the flange 24 and the gasket v 16; The head 27 has an inlet orifice formed therein which is 'adapted to register with the discharge orifice 22 of the gasket 16, and is usually provided with a springpressed closure not shown.` The particular construction of the lubricant receiving device forms no part'of inypresent-invcntion, which is capable of being used in connection with other well-known types of luricant receiving devices forming parts of systems such as described in general terms in the introductory portion of this specification In using the improved compressor describedv above, the operator merely grasps hold of the barrel 5, and by reason oi the rigid discharge conduit 9 and its rigid con` nection with the barrel of the compressor, he is enabled to position the coupling member at any desired point,.even if this necessitates inserting the conduit into a relatively smallv opening or space. 'It the ring 17 and the collar 18 are adjusted towaid each other sufiiciently, the friction between the spherical head and the gaskets will be sufiicient to enable the operator to manipulate the bifurcated portion ot the coupling member aboutl the tubular portion of the lubricant receiving device without touching the coupling member. Otherwise, it will be necessary for him after having properly positioned the coupling member to use one hand to properly position it with respect to the lubricantreceiving device. When this has been done, the compressor and the lubricant receiving device will occupy the relative positions shown iniFigure 1, which shows lthe outer portion vif the gasket 16 upon flow through the discharge conduit 9 and the passageway extending through the head 11 out'thiough the branch passages 1l and into the space between the flattened face 13 and the gasket 16. The pressure of the lubricant thus exerted' upon the inner side of the gasket 1G will press it outwardlyi into tight contact with the adjacent face of the lubricant receiving device, and establish a thorough seal. The lubricant will lthen pass through the disicharge orifice 22 into the lubricant receiving device. When it is desired to disconnect the'eonipressor from the latter device the handle is rotated to relieve the pressure on the lubricant in the barrel 5 and. thev coupling member can then be easily disconnected from the lubricant receiving device.

vI claim is:

1. A lubricant compressor comprising a receptacle for holding lubricant, a rigid'discharge conduit rigidly connected therewith,

thel free end of said conduit being turned at an angle theretoand ending in a spherical hcad wiring a -flattened face, said headv4 being profiled with a passageway communicating with said conduit and opening through said flattened face, a coupling` member universally mounted on said head and rotatable relatively thereto, and an apertured gasket extending' across said flattened face in spaced relation thereto. i

2. A lubricant compressor comprising a receptacle for holdingllubricant, a rigid dischar e conduit rigidly connected therewith, the tree endof said conduit ending in a spherical head having a flattened face, said `head being provided with a passageway communicating with said conduit and opeibl ing through said flattened face, a coupling member universally mounted on said head, and an apertured gasketextending across said flattened face in spaced relation thereto.

3. A lubricant compressorcomprising a receptacle for holding lubricant, a rigid discharge conduit rigidly connected there` with, the .free end of said .conduit ending in a spherical head having a flattened face, said head being provided with a passageway meeste communicating with.- said conduit and opening through said liattened face, a coupling member rotatable relatively thereto, and an apertured gasket extending across said flattened Jface in spaced relation thereto.

4. A lubricant compressor comprising a receptacle forV holding lubricant, a rigid dis` char e conduit rigidly connected therewith, the ree end of said conduit ending in a spherical head having ak flattened face, said head being provided with a passageway communicating with said conduit and opening through said flattened face, a coupling member rotatable relative thereto, and an apertured gasket extending across said flattened face.

5. 'A lubricant compressor comprising a receptacle for holding lubricant, `a rigidv discharge conduit'rigidly connected therewith, the free end of said conduit being.

bent at an angle thereto and ending in a member having a lubricant discharge opening, a flexible gasket extending over a portion of said member in spaced relation, and means for making `a detachable connection with a lubricantreceiving device, the said connecting means being universally flexibly mounted and comprising means for holding said gasket against one face of said lubricant receiving device. l

6. A lubricant compressor comprising a receptacle for holding lubricant, a rigid discharge conduit rigidly connected therewith, the free end of said conduit being bent at an angle thereto and ending in a member having a lubricant discharge opening, a iexible gasket extending over a portion of said member in spaced relation, and means for making a detachable connection with a lubricant receiving device, the said connecting means comprising means for holding said gasket against one face of said lubricant receiving device and being mounted to move in a plurality of directions relatively to said member.y

In witness whereof I hereunto subscribe my name this 27th day of January, 1921.
